LANTERN.

SPECIFICATION forming part of Letters Patent No. 589,588, datedSeptember 7, 1897'.

Application filed December 26, 1896.

To MIX IL /UHII. 11m. concern.

Be itknown that I, FRANK Tnnononn WIL- LIAMS, a citizen of the UnitedStates, residing at Meriden, in the county of New Haven and 5 State ofConnecticut, have invented certain new and useful Improvements inLanterns, of which the following is a specification.

My invention relates to improvements in lanterns; and the main objectsof my improve ments are to provide a simple arrangement of the devicesfor seeu ring the lamp to the la ntern-body, so as to properly locatethe lens with reference to the burner, and to provide simple andconvenient means for removahly securing the cover-glasses for either theback reflector or the lens, or both.

In the accompanying drawings, Figure l is a side elevation of mylantern. Fig. 2 is a sectional elevation showing the lower end of thelantern-bodyand upper part of the lamp. Fig. 3 is a side elevation of aportion of the lamp, showing the fixed holding-lug. Fig. 4: is a planshowing the lower end of the lanternbody. Fig. 5 is a sectionalelevation showing a modification in the holding devices. Fig. 6 is aside elevation of a portion of the lamp, showing one of said holdingdevices. Fig. 7 is a central vertical section of the lanternbody,looking toward the back deflector. Fig. 8 is a horizontal section of thelantern-body on the line :1:- of Fig. 1; and Fig. 9 is a detachedelevation of the lens-tube, showi ng the cover-glass at its smaller end.

A designates the lantern-body, and B the lamp, both of which as to theirgeneral features may be of any ordinary construction. The lower end ofthe lantern-body is provided with an inwardly-turned horizontal flange10, having one or two (preferably two) radial slits 11, Fig. 4.. Thelamp B has its burnerdeck or upper end fitted to the interior of theflange 10 and is provided with a horizontal ledge or shoulder 12, uponwhich the lower end of the lantern-body may rest. At one side of thelamp, above the shoulder 12, is a fixed holding-lug 13 andv a verticalwing 14:, the said lug being adapted to receive the flange 10 under it,while the wing is received in the radial slit 11, if there be but oneslit, or in one or the other of said slits, in case there are two. Theflange can be made to enll register with said wings.

Serial No. 616,977. (lie model.)

gage these parts by tipping the lantern-body a little and presenting thelowest point in the flange thereto from one side. Diametrically oppositethe wing 14; of the [ixed holding-lug 13 is a sliding and beveled latch15, that is forced outwardly by the spring 16 and inwardly by thepressure of the flange 10 on its beveled end or by pressure on thepush-piece 17, as in ordinary latches of this class.

It will readily be seen that the slit or slits ll and wing 14, beingproperly located with reference to the lens-tube l8 and the lampburner19, will always locate said lens in its proper relation to said burner,while at the sametime the lantern-body is of a very simple construction.If there is only one of said slits, the lens must always stand in oneposition with reference to the lamp. If there are two such slits, it canstand in either of two diametrically-opposite positions; but in each ofthese positions it will face the broad side of the wick-tube, and hencebe in the proper position with reference to the burner.

I do not claim devices for locating the Iantern-body with reference tothe burner, but only claim such devices as are illustrated and describedin connection with a lantern-body having the flange 10 and holdingdevices for looking over the top face of said flange.

If desired, I can employ two latches, each having vertical wings let, asshown in Fig. 5,

said wing being fixed on the latch and moving with the same as if formedin one piece therewith.

It is evident that the spring-latches herein shown and described on theleft-hand side of Figs. 2 and 5 are interchangeable without anymodification whatever.

lVith two spring-latches the lantern-body may be forced down upon thelamp without any reference to the position of the lens, the said bodyacting to force the latches inwardly against their springs. The wings,however, will prevent said latches from properly en- 5 gaging the top ofthe flange 10 unless the slits If they do not so register, thelantern-body is rotated on the lamp until the slits come in front of thewings and the springs force the latches into engagcmo ment. The lenswill then he in its proper re lation to the burner.

The back reflector JO'lias its edges resting on one side of thelantern-body, and in front of said reflector I arrange the cover-glassslide 21 back of suitable lugs or pins 22. so

that said slide may readily he slipped into place and removed. Saidslide is provided with a circular opening surrounded with a shallowrecess or depression that receives the cover-glass 23. with two lugs 24:near its lower end.

Said slide is also provided I detachably secure the cover-glass withinthe slide by means of a wire sprin 25, bent into a circular form, butextending only over about three-quarters of a full circle. The ends ofthe wire are then bent outwardlyto form ing or other purpose andreturned again by.

slipping itdown under the wire spring. The connection of the two ends ofthe spring with the cover-glass slide at widelyseparated points formssuitablestopsto properly seat the cover-glass in position as it ispressed down.

\Vhile I prefer the lugs 2i for attaching the wire spring, it is evidentthatthe ends of the spring could be secured in the same position bysoldering. In Fig. 9 the ends of such a spring are illustrated as merelysoldered in place. A slide and cover-glass, as illustrated anddescribed, may also be used recover the inner end of the lens-tube. lhave, however, illustrated the lens cover-glass 27 as seated directly inthe inner end of the lens-tube 18 and held therein by a wire spring 25,substantially like the wire spring 25, only its shanks 26 are solderedin place instead of being secured by means of perforated lugs. It

is evident that a cover-glass and its holder,

asherein illustrated and described, for the lens could be secureddirectlyto the back deflector.

. By this improvement in holding the coverglasses the con structi on issimple and inexpensive. The covei glasses may be readily lifted out ofplace for removal when desired and readily placed. They are also veryeflieiently held, and held under such a yielding, gentle, and evenpressure that they are not liable to break.

I claim as my invention 1; A lantern the lamp of which has upon one sidethe fixed holding-lug 13 and vertical wing it and on its opposite side aspringpressed latch andthe body of which lantern is provided at itslower end with the inwardly turned flange iO'ha-ving a radial slit 11,the said lug 13 and latch engaging said flange over its top face whilethesaid wing it enters the said slit in said flange substantially asdescribed.

2. A lanternhaving a cover-glass fitted to a recess in a suitablesupport anda wire holding spring extended in circular form for aboutthree-quarters of a circle and secured by its two separated ends to saidsupport with its free circular portion otherwise disconneoted from saidsupport and adapted to bear on the said cover-glass near its edgesubstantially as described.

3. In a lantern the cover-glass slide having a circular opening andcorer-glass seat with perforated lugs near the lower corners of saidslide, the cover-glass fitted to thesaid slide. and a wire springembracing the major por tion of a circle for resting on said cover-glassnear its edge and with. outwardly-bent shanks extended through the holesin said lugs and permanently secured thereto substantiallyas described.
